APPARATUS FOR DRAWING OFF BEER FROM BARRELS.

SPECIFICATION forming part of Letters Patent No. 781,813, dated February'7, 1905.

Application filed August 30, 1902. Serial No. 121,677.

To (1, 10710721 it may concern:

Be it known that I, Josnrn Dnnarrrnn, a citizen of the French Republic,residing at La toconniere, Laval, France, have invented certain new anduseful Improvements in Apparatus for Drawing Off Beer from Barrels, ofwhich the following is a full clear, and exact description.

The object of this draw-otl' is to entirely prevent t'rothing, the beerpassing from the barrel into the bottles without any depression. Forthis purpose the counter-pressu re in the cylinder and bottles is nolonger produced'by the beer, but by a liquid termed the compensatingliquid, (glycerinated water.) As the beer does not froth, two cocksinstead of tour or six are amply sutlicient, and the operator is enabledto etl'ect the drawing off while seated. Finally, the cocks, which arevery simple and strong and easily operated, are completed by anapparatus for automatically drawing otl' the froth. The nozzles ofthecocks are provided with an inverted-cone trunk made of flexibleindia-rubber, which elfects a junction with all the bottle-necks evenwhen the latter are indented.

In order that the object of the invention may he understood. it isillustrated in the accompanying drawings, in which- Figures 1 and 2 arerespectively a front and a side view of the machine. Fig. 3 is alongitudinal section, on a larger scale, of one of thedistribnting-cocks; Fig. l, a transverse section of the same; Fig. 5, aview of the same from below; Fig. 6, an end view of the same on the sidewhere the machine is worked; Fig. T, a view in detail of the means ofworking the screens: Fig. 8, a detail view ot' the means of working thedistributing-cocks combined with that of the screens.

The machine thus illustrated is composed of a cast-iron table a and twoframes 6. Through this table run the rods 0 of two platforms (Z, movablein guides. Each platform is raised by a counterweighted lever 1 the endof which enters a slotin the guide. These platforms,

In order to release the botties, the levers c are lowered by pedals 71,the fulcrums of which are jointed to a com p resscdgas reservoir i'.This reservoir f, whichconnects the two frames 6, is filled two-thirdsfull with glycerinated water, (compensating liquid.)

Z is a junction intended for the india-rulr ber tube which conveys thecompressed air or carbonic acid from the gencrating-receptaclc to thereservoir 1 is a d ischarge-cock for conveying the compressed gas ont off as required and causing the compensating liquid which has risen in thecylinder m to descend.

A pipe 11 starts from the bottom of i and runs through the column I) tothe glass cylinder m. The float 1) is arranged to close the opening 1running to the outside of the cylinder. The pipes I connect the upperpart of the cylinder with the air-passages N, cut through the cocksFigs. 3 and t. These cocks, which have conical plugs and are screwed upmore or less tightly by a nut? and a washer n, Fig. 5, have two passagesof unequal diameter running through them. The one w, of six to sevenmillimeters in diameter. conveys the beer through the junction situatedbehind the column and through the interior of the arms which support thecocks. The compressed-air tubes r are extended. as mentioned above. bythe passages x, which are divided in the plug of the cock into twooblique passages connected by another passage 11*, and thus forming atriangle. The base 1/ of this triangle is in constant commnnication withthe pipes, while the apex of the triangle is alternately incommunication with an apparatus for drawing otl' foam and with thebottle to be tilled. Under this arrangement the compressed air entersthe empty bottles well in advance of the beer, and as soon as the airand the beer meet in the bottles the passages in the plug of the cockcommunicate with pipes .r, which lead to a three-way cock .1 and theoutlet-opening of which is also t'urnished with an india-rubber cone.against which the neck of a bottle 1 (its and into which the froth isdischarged. This bottle is supported and held under the cock .1 by abalance-lever The opening and closing of the distributingcocks g, Figs.2 and 8, are effected by levers pivotall y connected withconnecting-rods a which actuate the keys 7), solidly connected with thecocks g.

Screens 0 are arranged vertically between the platforms (Z and thedistributing-cocks, their opening and closing being effectedsimultaneously, but inversely with the opening and closing of the cocksg and by the simple operation of the levers .2 described. For thispurpose the bottom of each of the connectingrods forms a projection a onwhich a lever 2" rests, the end of which opposite to the pivot is raisedby a belt cl, which passes over a pulley (Z and thence around a pulleye, the axis f of which is the pivot of the corresponding screen. Fromthis pulley the belt passes over a second vertical pulley g and supportsa counterweight 7a, Fig. 7,

The bottom of the connecting-rod (0, already described, may assume thepositions (0 (0*, and 0f. In Fig. 7 the bottom a has returned to a andnearly closed the cock 9. In raising the rod from (f to a the levereffects the closing of this cock. In Fig. 7 the cock 9 is closed and thelever 2 is about to lower the rod from a to a", which effects theclosing of 0. Then when the lowering is continued from (0* to a the keyI) will fall to 72 Fig. 8, the opening point of the cock whichcorresponds to a IVhen the cylinder m is arranged a little above thecooks g and these cocks being at a suitable height to permit the workmanto work while sitting down, the compensating liquid must necessarily beabout the same density as the beer. T he density might beless if thecylinder were higher, and, on the contrary, this density might begreater than that of the beer if the cylinder were lower, (which wouldinterfere with the manipulation of the bottles.) Thus the density of thecompensating liquid need be about the same density as that of the beeronly in case of the practical arrangement of the parts as seen in thedrawings.

Action: From the foregoing it will be seen that the compressed gas mustfirst be conveyed from the generating-receptacle, which is independentof the machine, into the reservoir 7'. Under its action the compensatingliquid rises in the cylinder m, raises the float, and forms in the upperpart of the cylinder a second air-chamber, the pressure of this airbeing lower than that of the generating vessel by the whole weight ofthe column of liquid between i and m. The compressed air in the cylindercreates the counter-pressure in the empty bottles through the pipes 1'and the passages 1.0 in the cocks. The beer in turn. reaches thebottles, and as it is forced by the same compressed-gas receptacle asthe com-, pensating liquid and has less distance to ascend than thelatter itdrives the air contained in the bottles before it, fills thebottles, and

if the closing of the cocks be not effected rises again in the pipes ronly up to the level of the float 22. hen the quantity of air forced outof the bottles into the cylinder becomes too large, the compensatingliquid sinks with the float p, which then allows the excess of air toescape through the orifice q. The beer which has been able to ascendagain in the air-pipes 1* runs off during the closing of the cocks intothe froth-receptacle y through the pipes This beer cannot thusbedischarged in a foaming condition into the fresh bottles to be filledand is recovered in 1 What I claim is 1 1.
